Allegiant Air to Expand to 99 Cities

Allegiant today announced new service on 18 routes, bringing to 99 the number of cities served by the Las Vegas-based carrier. That’s more cities than Southwest serves, but Allegiant offers a few flights a week on most routes, whereas Southwest typically operates several flights or more every day.

Launch dates vary by route, but all the new services will be in place by the end of the year, using newly acquired Airbus A320 jets.

Allegiant is an ultra-low-cost carrier, like Spirit, focused on leisure travel to smaller airports. And like Spirit, its financial performance has been significantly better than most other U.S. airlines’.
